1 The "lying" periods were all run on another respiration apparatus located on the third floor of the labora- 
tory. The subject went downstairs to the first floor for the work periods and then returned to the 
third floor. The ventilation of the lungs was measured while the subject was on the couch. 
J The respiration rate while the subject was on the couch was for the full period, as recorded by the spirometer. 
J The subject said at the close of this period that he had a headache. His forehead was bathed in perspiration. 
« Work was started at 9 h 57 m a.m. Between 9° 57™ a.m. and lO* ll m a.m. the average speed was 104 revolu- 
tions per minute. 
* Between the periods the average speed was 82 revolutions per minute. 
« Work was finished at lO 1 " 55 m a.m. The subject immediately left the ergometer, hurried upstairs, and lay 
down on the couch.

1 The metronome was used in each period to regulate the speed. 
J Work was begun at 8» 06 m a.m. Between S n 06 m a-m. and & 43™ a.m. the average speed was 70 revolu- 
tions per minute. During the period the work was done with perfect ease. There was no strain 
whatever. The subject said he scarcely felt the work. He said he had been at Revere Beach on 
Apr. 7 and had ridden 10 miles on the track at the rate of 1 min. 35 sec. to the mile. He had done 
this with absolutely no difficulty. His opinion was that one hour's work on the ergometer was equiva- 
lent to about 50 miles on the track. 
* In the interval before this period the average speed was 66 revolutions per minute. During the period the 
work was done without difficulty. 
* In the interval before this period the average speed was 70 revolutions per minute. During the period the 
work was done with ease. 
6 At 9 h 45 m a.m. the speed was increased to 120 revolutions per minute. Between 9 h 45™ a.m. and 10 11 12™ a.m. 
the average speed was 90 revolutions per minute. During the period itself the work was done at 
tremendous speed toward the end. At the end of 7.5 minutes the subject lost a pedal and picked it 
up again. Perspiration was not very profuse. 
« In the interval before this period the average speed was 76 revolutions per minute. During the period the 
work was done with greater difficulty. The subject found it harder. Perspiration was very profuse. 
1 The pulse was very rapid in this period, no satisfactory count being possible. 
8 In the interval before this period the average speed was 70 revolutions per minute. During the period the 
work was done with comparative ease. It was much lesa trying than in the preceding period. 
9 Pulse-rate at the end of the period.
